This would be good to know if you are seeing the exact same issue here. Helmut, IIRC you already did write some debug code and investigate about retrying the i8042 reinitialization if it failed. Did you ever find out more about this issue? Maybe your preliminary debug patch can help the i8042 experts to cook up something helpful for this issue.

Not yet as I cannot reproduce this issue reliable it's really hard to get a clue. But my assumption is that i8042_command writing the CRT times out and therefore fails to restore the device correctly. As s2ram works now I'm trying to do some more tests. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

To the i8042 gurus: can't we just in case of the "Can't write CTR to resume"-problem try once again? or do the equivalent of an unbind / bind operation? This is a really nasty problem, because usually when this happens, the only thing you can do is reboot via powerbutton, since you have no input device left to do anything to recover the machine. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I only use s2ram but I don't know if we are having the same issue as I also checked hwinfo --keyb , which is telling me usbhid is being used for keyboard and mouse. Guess that means I had a different issue? :/ As for the 'nastyness' it might be an idea to have a usb mouse handy (and also a app icon that does a dmesg > textfile.txt or similar).

[21993.796930] i8042: probe of i8042 failed with error -5 I tried enabling i8042.debug, but this did not do anything (probably because there was no i8042 to debug anymore ;-) So i did another suspend to RAM, resume, and after that i retried the unbind / bind trick, this time with success (and lots of debug). The dmesg of this session is in the attachment. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I have raised this issue with Dmitry (upstream), to come up with proper workaround. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

You still will only see half of the story in dmesg, since the "boot until image is loaded" part will be gone, but we will see if we find out something with that. Having debug on all the time is unfortunately not really doable :( -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

It performs one retry on CTR write on resume path. It should be acceptable upstream, if it fixes the problem.

What happened this time is: suspend to disk => keyboard gone pressed power button (configured to unbind / bind i8042) => does not help retried several times, without success plugged a USB keyboard / mouse executed suspend to ram after resume, still no keyboard => because the controller was already gone, there was nothing to reinit pressed power button again => keyboard and mouse reappeared. I enable i8042 debugging before suspend and disable it after resume, so there may be information in there on why it fails. Should i also enable debugging before the unbind / rebind procedure to get more information? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

In 2 of 40 attempts I got the message "i8042: Can't write CTR to resume, retrying ..." and the retry succeeded. It seems as one retry is really enough and fixes this issue at least for me (HP 2510p). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
